[AccessD] update query using values from a query

I am trying to do an update query updating a table with the values from a
query. I get the message that "Operation must use an updateable query"  so
it won't run. But I am not trying to update the query! I'm just wanting to
use the values from the query to update the table.

==========That error means you can't use the query to update the underlying
table. Not every query is "updateable." There are rules and I'll send you
something privately.
